Thanks for reviewing this! Yea that's one of the drawback(Added FIXME for the same). Since I've used `dbg.value` intrinsic for representing this variable(all reduced scope variables), this is resulting in a location list entry. We should avoid this somehow, this is because, In our local `GDB` implementation `DW_AT_start_scope` is the only thing necessary for capturing the scope info correctly.
BTW, as per @dblaikie comment, do `llvm-dwarfdump` needs to be aware of `DW_AT_start_scope` ? How does it calculate size ? Getting the raw section size(that should capture `DW_AT_start_scope` too) ? Or some other mehachnism ?
